Featured Social casino, US, 500K+ users

KNTX

KNTX runs a 500,000-user social casino. Its email program had decayed: open rates had fallen to 13%, click-through to 0.01%, and roughly a fifth of the database was unreachable. Folderol cleaned the list, recovered IP reputation with a staged secondary IP, rotated templates and content, and aligned SPF, DKIM and DMARC under continuous monitoring.

“When deliverability drops, engagement drops with it. Restoring that infrastructure had a direct impact on our marketing performance.”
